Water flow meter technical articles
In order to improve the quality of water supply and safe water supply, and reduce the cost of production operations, the water plant will establish an automatic monitoring and auxiliary dispatching system to provide water distribution projects with automatic monitoring, real-time production scheduling, systematic management and standardized services.
Through the construction of a modern water supply dispatching system, a pipeline network monitoring network and a control communication network are established to ensure that the actual monitoring value of the key points of the water supply system is remotely measured and collected to the dispatching center, which is displayed on the computers of the departments authorized by the functions so that the departments can understand the production situation in real time. .
The tap water flow data acquisition part of the system needs to use high-precision flow meter - electromagnetic flowmeter
The electromagnetic flowmeter is based on Faraday's principle of electromagnetic induction. A pair of detection electrodes are installed on the wall of the pipe perpendicular to the axis of the measuring tube and the magnetic force line. When the conductive liquid moves along the axis of the measuring tube, the conductive liquid cuts the magnetic lines to generate the induced potential. The potential is detected by two detection electrodes, and the magnitude is proportional to the flow rate, thereby detecting the flow of the liquid.
A dedicated water meter-magnetic flowmeter is installed in the pipe network to detect the instantaneous flow and cumulative flow of tap water in real time, and upload the collected data to the control system or computer for monitoring or adjustment.
Cooling tower generally comes with water cooling type chiller, as heat rejection device used to transfer process water heat to the atmosphere.
Cooling towers are used in various industries such as power plants, chemical plants, paper mills, steel mills, refineries, oil & gas processing, and food processing. They are also used in many commercial buildings and large residential complexes, popular in HVAC systems for cooling and dehumidifying air.
